hi pos coiner
i want to know if it is possible to mine pos without used gaz ? because i think this isn't profitable if i mine pos by ether transaction..you know wht it is

i can mine 15 POS rewards but if i do an ether transaction for extract them i will be loser..15X0;25POS=~3,5$ it's really small i will do an eth transaction by smart contract an used 200 000 GAZ may 2$.
i exctracted my pos and i used 110 000 GAZ at 21 gwei ~1,1$ i think this isn't interessting because i loss 1,1$ ~4 POS this is really priced

You can conduct a transaction by installing GasPrice 1Gwei. It will take a long time but you will spend very little money. Many people do this, there is nowhere to hurry.
